Am I pregnant? Implantation bleeding or period??

Zu

So my s.o and I had unprotected sex during my fertility window just over a week ago. There was only precum & I took plan B immediately. After that the only symptom was slight cramping. Ever since then ive been experiencing nausea, dizziness, mood swings, extreme hunger (extreme!!!) frequent peeping, back pain & all over body aches. Pretty much the symptoms of both pregnancy and period.

I thought I started my period a couple days ago, but it just stopped which makes me think it was implantation bleeding. It was a bit of blood but now there's only a little bit of pale red/pink colour when I wipe.

If it's obvious that I'm not! Please don't bash me, I'm a very intuitive person and I genuinely feel like something isn't right with my body at the moment. Any comment would be helpful thank you !
